Lo & Co Marble Hubble Knob is a spherical shaped knob crafted from marble with a beautiful honed finish. The small measures 40mm in diameter and the large measures 60mm in diameter. We note these stunning handles are crafted from natural marble and therefore their veining is irregular and adds to the beauty of this product. Lo & Co Dot Marble Hubble Knob is available in seven marble finishes; Black, Carrara, Tundra Grey, Rosso, Verde, Calacatta Viola and Travertine.
